I dealt with Bruce about 7 yrs ago. I went to him to build a 600HP stroked 455 tri power. for my GTO,
Had the engine in my car for about 18 months. It was broke in correctly and driven aout 2500 miles> At that time I felt it was broke in correctly and started driving a little harder.
I brought the motor to 4500 rpm twice before it blew, Oil pressure went to zero. I had a very reputable engine shop take it out to find the cause, what they found was astonishing.
The cause for loss in pressure was that he did not reinforce the oil pump shaft, allowing it to come loose and wreak havock in the engine block. After taking to the the shop in charge of correcting the problem, they said it is a standard on Pontiac engines, set up for race or high output street to do this.
Here is a list of what Rock n Roll/Bruce Fulper cheated me out of:
Block was not decked
Stock rods
Stock pistons
Stock rings
Head gaskets were not sized to balance engine
No balancing was done on any components
The engine was not stroked
Not stroked crank
Not stroked rods
Stock head bolts
Engine was not balanced
Checks were done on all bearing clearances and did not meet crate engine levels
As a final analogy i paid 12,800.000 dollars for a 4,500.00 crate engine. In his defense he did supply requested Kaufman heads that he did port.
Anything else that was hidden he cheated on. Bruce does no his stuff in the Pontiac world, but would highly recommend, if he does any work for you. That you live at his shop to make sure you are not getting the same and truly are getting what you paid for.
After my engine was rebuilt, by a company that actually did the work that was promised, I finally have the GTO I dreamed of. The engine did a rear wheel dyne at 550hp and I'm thrilled.
